Individual performance optimization of electronic lens for presbyopia correction

Abstract

An optimization system for presbyopia correction includes a dynamic lens and a separately disposed controller. The dynamic lens includes a sensor measuring an ocular element of a person's eye, a control electronics, an actuator, and a presbyopia correcting optical element communicating with the actuator for its setting to a far or near optical power. The controller sends paired instructions synchronically to the person as an audio command for viewing the object at far or near distance and to the control electronics as a wireless command to send the actuation signal to the actuator for communication with the presbyopia correcting optical element. The control electronics receives the wireless command and the sensor signal, stores the sensor signal, sends the actuation signal to the presbyopia correcting optical element and stores the corresponding actuation signal. The actuation signal communicates to the presbyopia correcting optical element to set for far or near optical power.

No: 62 / 983,753 filed Mar. 2, 2020, the entire contents of which are fully incorporated into the present application with this reference.DESCRIPTIONField of the Invention[0002]The present invention relates generally to a presbyopia correcting lens that changes its optical power by a surface shape, material refractive index or relative movement of a lens parts under the action of an ocular element of the eye. More particularly, it relates to an electronic presbyopia correcting ophthalmic lenses such as eyewear lens (EL), intraocular lens (IOL) and contact lens (CL) that change their optical power with optical surface shape, optical material refractive index, and / or a relative movement of lens parts. In addition, the present invention relates to a wireless communicati...

Benefits of technology

The patent text discusses different options for powering small devices, such as eyewear lenses. One option is to use a thin film rechargeable solid-state smart battery, which can be integrated with microelectronics into a single package. Another option is to use a photocell that can be combined with a capacitor for energy storage. The text also mentions the use of transparent photovoltaics that capture both visible and UV light, as well as the use of inductive recharging. The text also mentions the potential use of gallium nitride semiconductors, which are more efficient than silicon semiconductors. Overall, the patent text provides various options for powering small devices and offers potential for improved efficiency and cost-effectiveness.

Problems solved by technology

Nevertheless, the issue remains in providing far and near foci optimized for any given individual wearer because a sensor signal may vary significantly depending upon a dynamic lens placement, anatomical features of the wearer, physiology of ocular element interaction with it by the dynamic lens results in an optical power change.

The option currently used involves a wearer to continually control a signal for power change which is inconvenient, deferring a wearer from other tasks and prompt to delay of the focusing itself.
